Jiraiya so far seems to belong there.
As for as the previous list.....
Kakashi doesnt belong in here
Hiruzen doesnt
Minato doesnt
The Uchihas have above average chakra in terms of quantity, but where they are consired beast is in the Quality of it.
So Sasuke doesnt belong here either, not more than Itachi as they pulled the same amount of things in their respective fight as far as MS usage goes.
Madara is an edo, we have yet to see what he has in terms of stamina.
Senjus and Uzumakis are natural chakra beasts.

Hashirama
Tobirama (likely)
Kushina (likely)
Naruto
Bee (maybe, excluding bijuu that is)
Gaara
3rd raikage
